HTML pre Tag

The HTML <pre> tag is used to define preformatted text, which preserves the original formatting and spaces within the text. It is commonly used to display code snippets, ASCII art, or any text that requires a fixed-width font and precise spacing.

Here’s an example of how the <pre> tag can be used:

<pre>
     function greet() {
          console.log("Hello, world!");
     }
</pre>

In the above example, the <pre> tag is used to enclose a code snippet. The content within the opening and closing <pre> tags is displayed exactly as it is written, including line breaks and spaces. It ensures that the text is rendered in a monospace font, maintaining the formatting and indentation.

The <pre> tag is especially useful when displaying code examples or preserving the layout of text that relies on whitespace, such as ASCII art or table structures.

It’s important to note that the content within the <pre> tag is typically rendered without any modifications, so you need to manually format and indent the text as desired. This also means that any HTML tags within the <pre> tag will be treated as plain text and not interpreted as markup.

Additionally, the <pre> tag preserves multiple consecutive spaces, allowing you to display text with precise spacing. However, leading and trailing spaces within each line are trimmed unless explicitly included within the content.

The <pre> tag is a valuable tool for displaying code snippets and maintaining the original formatting and spacing of text within an HTML document. It ensures that the text is rendered in a fixed-width font and provides a convenient way to present preformatted content to the user.
